The game always runs at 30FPS despite 60FPS being an option in the graphics settings, the game requires the most useless launcher created by man, and has a forced always-on DRM for a nearly 15 year old game.

The Rockstar will forcibly install on your drive a lot of unnecessary things including the launcher. Then they'll force you to create an account you don't need and mockingly ask you if you would like to link your Rockstar and Steam accounts, but you won't have the option to say no.
We should be warned about such impudence before purchasing; then many people will definitely refuse.
I didn't return the game , but decided to express my opinion. The game itself is not bad, but it's very old. The graphics aren't great. Characters look past each other during interactions and move unnaturally during the fights. The city, however, looks pretty good. The gameplay is decent. I liked the voice acting. Overall, if I'd read the review beforehand, I certainly wouldn't have bought the game. Although since I bought it on sale the loss was small.

又臭又长的侦探剧游戏，案件基本公式化流程，至于根据表情判断证人是否撒谎更是一个噱头，即使判断失败也不会影响案件流程的触发，唯一能影响的只有案件结束后警监对你的语气以及之后的打星评价环节。最让我恼火的是凶杀科的所有案件， 一路下来发现嫌疑人全部抓错而且真凶在犯罪动机和犯罪手法不明的情况下在警监短短几句话下就让他逍遥法外。 能忍住继续玩下去的也是神人了，唯一的亮点也就是对战后美国的氛围塑造还不错，跟mafia一样为了一个线性故事捏了一整个假大空的城市，但游戏本身的故事也就一潭死水那种，我的耐心已经耗尽。
